"tapes-thereto; mken mmthe-=-1me+ pump I is power driven by an engine l3. Thus upon turning of the valve 8 to either of its positions, liquid will be pumped from the reservoir [2 by means of the pump l0 through the tube 1 into the chamber of the cylinder 6, or the liquid will bleed from the chamber in the cylinder 6 through th tube 1 and the valve 8, directly into the reservoir t2 through the connection II, this bleedin :being accomplished by gravity acting on the burners supported on the cylinder 6, as hereinafter described.

The burners are shown as supported by a series of pipes extending outwardly in opposite directions from the respective hydraulic lifts 4, three pipes being shown on each side of the conveyance as indicated at l4 and I5. However, any suitable number of pipes may be used according to the number of burners desired for the mechanism. The pipes l4 and are held in parallel spaced relation by transverse bars l6 and I! located respectively at the inner and outer ends of the pipes 14 and 15. The pipes l4 and I5 are journaled in the bars I6 and I1, capable of rotation relative thereto, but are adapted to be locked in adjusted positions by means of set screws l8. 7 Each of the pipes l4 and I5 is closed at its outer end, while th inner ends thereof are connected I with air supply ducts l9 leading to a blower driven by the engine 13, as shown in Fig. '7, whereby air will be supplied under pressure to the respective air pipes l4 and 15. The burner assemblies, one on each side of the trailer, are adapted to be supported by the hydraulic lifts 4. As shown, the inner'end of each burner assembly is mounted on the lift 4 in the manner illustrated in Figs. 2 and 4. The pipe I4 is extended and connected by a swivel 2| and a pivot 22 to a lug 23 welded or otherwise rigidly fixed to a side of the cylinder 6. The swivel 2| comprises a plate se-- cured to the end of pipe l4 and rotatabl therewith and said plate is positioned within a socket in said swivel with a retaining ring threadably retaining said plate against outward movement. This swivel arrangement will permit the plate mounted on the pipe to rotate within the socket of swivel 2|. A set screw for engagement with the plate on the end of pipe I4 is provided to hold the pipe in adjusted position. This will allow both for rotation or turning movement of the pipe 14 to accommodate a tilting action of the burners as indicated by dot-dash lines in- Fig. l, and also for swinging movement about pivot 22 of the entire burner assembly to accommodate for irregularities or variations in slope of the surface of the road or field on which the burner mechanism may be operated, as is often desired. v

The lug 23 is bifurcated at 23a to form .outstanding lugs, as will best be seen in Fig. 2, to receive a'complementary lug 2 la formed on the inher end of socket swivel 2|. A set screw 21b threadably engages socket swivel 2| and projects therethrough to interengage the plate l4a welded ,or otherwise secured to the inner end of tubular support member I 4. A threaded bushing 2 lo surrounds tubular support means [4 and threadably interengages the swivel socket 2| so as to hold tubular members I 4 and I5 in fixed relation with respect to hydraulic cylinder 6, when set screw 2 lb is secured in place. i

The outer end of each burner assembly is supported by a lug 24 connected with the outer end of the pipe l4, and a flexible device 25 that extends from the lug 24 to a hook 26 attached to the upper end of the cylinder 6. This flexible device 25 is shown as including a section of chain,

the surrounding atmosphere.

4 the length of which may be adjustably connected with the hook 26 to vary the length of the flexible device, thereby to raise or lower the outer end of the burner assembly.

In the form illustrated, each of the burner assemblies includes a multiplicity of burners adapted for burning gaseous fuels, such as butane, propane, or other form of liquefied gas, although other types of gaseous fuels may be used if desired. In the form illustrated in Figs. 3 and 6, each burner includes a burner tube 21. The burner tube 21 is open at opposite ends, and is mounted in an upright position so as to receive air in the upper end thereof and to direct the flame from the burner in a downward direction, according to the angle of the burner tube as illustrated in full lines and in dotted lines in Fig. 1. Each burner tube 2! is provided preferably with a jointless fire-clay 1ining 28, introduced therein under pressure and baked.

The burner tubes 21 are mounted in pairs along one side of each pipe l4 and I5 as shown more clearly in Figs. 4 and 7. Each pair of burner tubes 21 is supported by a connecting pipe 29 that extends therebetween as shown in Fig. 6 and coacts with an outlet pipe 38 to form a T. The outlet pipe 30 is in open communication at its lower end with the connecting pipe 29, and at its upper end has tubes 3| leading therefrom to nozzles 32.

Each nozzle 32 discharges into a mixing cham ber 33 in open communication with one side of the air supply pipe I4 or [5, for intimate mixture of the gaseous fuel and the air within the mixing chamber, which mixture then is injected into the burner tube 21 through a nozzle 34 which is disposed approximately axially of the burner tube and in position spaced from the surrounding sides thereof to allow freedom for admission of air through the adjacent'end of the burner tube from The T formed by the connecting pipe 29 and the outlet pipe 30 acts as a vaporizer for any liquefied fuel that reaches the connecting pipe 29, absorbing heat for vaporization from the burner tubes 21 in heat exchange relation with the connecting pipe 29 when th burners are in operation.

Fuel is supplied to the burners through a branch pipe 35 having a notch 36 in the lower end thereof, and which branch pipe extends downward through the outlet pipe 33 to the bottom of the connecting pipe 29 as shown in Figs.- 5 and 6. The upper end of the branch pipe 35 is joined to a fuel supply pipe generallyindicated at 31, which pipe 3! extends along the series of burners and to a fuel tank 38 shown in Figs. 1 and 7.

The fuel supply pipe 31 is connected with a tube 39 thatreceives fuel from the tank 38. The tube 39 may open into the top of the tank 38 and thereby withdraw vaporized gas from the top of the tank or it may form a dip tube extending to the bottom of the tank for the withdrawal of liquefied fuel from the tank which, in turn, is

vaporized in the connecting pipe 29 when the burners are in operation. Where vaporized fuel is withdrawn from the top of the tank 38, any liquid particles contained therein will be vaporized or re-vaporized in the vaporizer formed'by the connecting pipe 29 inheat-exchange relation with the burners 21. p

In the operation of the burner mechanism, the burners are first adjusted in position according to the character of thefwork to be performed, that isto say, whether the burner mechanism awe-:622:-

A high degree of efliciency is obtained thereby and a very hot flame results when discharged from the lower end of the burner tube downward toward the road surface or field where burning or heating may be desired.

With the burners thus operating, the entire burner mechanism may be drawn along the road surface or field by attachment of the trailer I to a tractor, truck or otherv conveyance, moving the burner mechanism over the surface Where the heating or burning action is desired. After thus accomplishing the desired heating or burning action, the burner mechanism may be moved by the trailer I to another point where such action is required or to a point of storage. This transporting may be accomplished effectively on the trailer, and to facilitate the movement along a highway, the burner assembly may be moved around to parallel relation, substantially as indicated by dotted lines in Fig. 7. Such parallel relation may be possible, especially when the burner assemblies are relatively wide, by raising one of the assemblies to a position above the other, as indicated in dotted lines in Fig. 4, which is accomplished by a lifting action of the corresponding hydraulic dirt-.14..- Themwhenzfurtheri usedszdesiredgit.isatsimpleunatteretci restore thac-v partsztothe :positiomindicated: in ',.they zdrawingsz ready-for.-zoperationiz.
